When a piece of sodium is put into water do you expect it to sink or float?
The density of sodium is 0.968g/cm3 which is just slightly lower than that of water, which is 1.00g/cm3. When sodium is added to water, the piece of sodium would float and sometimes dart around the sides of the beaker. It is a violent reaction and the heat evolved from the exothermic reaction is sufficient to ignite the hydrogen gas and cause the sodium to burn.
Why does sodium sink in water?
Sodium shouldn't sink in water at room temperature, because the density of sodium is less than the density of water. The density of sodium at room temperature is 0.968 g/cm3, whereas the density of water at room temperature is 0.998g/cm3. So technically, sodium should float in water, not sink.
Does feldspar float in water?
No, feldspar does not float in water because it is more dense than water. When placed in water, feldspar will sink to the bottom.
What is the word equasion for sodium in water?
sodium and water =sodium + water -> sodium hydroxide + hydrogen and this is the right answer because i got it of a scientist
Can asphalt float on water?
Asphalt is denser than water and will sink in water rather than float.
Why does float on water?
why sodium floats on water!!!sodium has to float on water as it is very reactive.
What are Two reactive metals that float in water?
The alkaline metals react with water, and Lithium and Sodium float on the water whilst reacting.

What two elements can float on water?
Two elements that can float on water are lithium and potassium. These elements have a lower density than water, which allows them to float on its surface.
What will float in saltwater but not float in tap water?
Objects that contain a higher density that water will sink, but if the same object has a lower density that saltwater, then it will float in salt water. And this also depends on the concentration of sodium ions present in the salt water. As the concentration of the sodium ions increase, the density of the salt water increases.
Which metals float on water?
Lithium, sodium, and potassium all float on water. Sodium and lithium both react with the water to give off hydrogen gas - they look a bit like fizzies when they do it. They can give off enough heat to light the gas, so they burn as they float around if there is enough oxygen to support a flame. I imagine potassium would act the same way, but I have never seen it personally. Beryllium, the lightest element in the alkaline earth group, is more dense that water, and would not float.
Sodium is under water metal?
No sodium is an extremely reactive metal that reacts violently with water. Sodium is in fact one of only two metals that is less dense than water, meaning that it can float on water. Whether a metal is underwater or not does not change its identity.
Which metal floats?
Lithium and sodium will both float on water, but not for long, because they're both explosively reactive with water.
Does an egg float in water with pepper?
Pepper floats because it is less dense than water.
Why does sodium sink in water?
Sodium shouldn't sink in water at room temperature, because the density of sodium is less than the density of water. The density of sodium at room temperature is 0.968 g/cm3, whereas the density of water at room temperature is 0.998g/cm3. So technically, sodium should float in water, not sink.
What is a metal that floats in water?
If you're floating metal on water, there are only a couple or three metals that have a density so low that they'll float on water. Those metals are lithium, potassium and sodium. Any one of these will float on water, and they are listed in order of increasing density with sodium just a bit less dense than water. Note that all of these metals will react violently with water, so we're setting this issue aside here. Be clear about that.
Is sodium density greater less than or equal to water?
At room temperature, the density of sodium is slightly less than that of water and it will, briefly, float (briefly, because it will be rapidly reacting with the water, and may in fact be on fire at the time).
